Yeah that's the Witch Doctor's biggest problems in a nutshell
1.Their basic attack COST resource. Barb/Monk/Demon Hunter generate Resource with basic attacks and Wizard's Missile is free. This makes no sense.
2.Wizard's abilities do more damage, cost less resource, and his resource generates faster.
3. Sacrifice is useless because of the Cooldown on Dogs. They last 5 seconds and the cooldown is one minute. All the moves that allow you to spawn dogs when people die require you to be super close. One problem with that: Witch Doctor has no damage negators or natural tankiness like Monk/Barb. It's counter intuitive.
The class just doesn't make any sense.
